TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Sept. 1, 1908. I

Application filed. January 11, 190%. Serial No. 188,656.

T all whom it may concern:

Be it known that I, BYRON 'A. BROOKS, citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the county of Kings and State of .New York, have invented certain new and useful Improvements in T ype-Writing Machines, of which the followingis a specification.

My invention relates to typewriting machines and more especially to devices andmeans for the application of power to an ordinary typewriter, such, for example, as the Remington No. 2 or No. 6, whereby the operator'is relieved of the bulk of the manual labor involved in the operation of the keys and entirely relieved of the return of the carriage to its starting point.

' My invention consists in the features of construction and combinations of devices hereinafter more fully described and particularly pointed out in the appended claims.

In the drawings accompanying this specification and'forming a part thereof, Figure 1 is a vertical longitudinal section of a typewriting machine with my improvements applied thereto. Fig. 2 is a rear view of the same with the base broken away to more clearly show theinvention. Fig. 3 is a plan view of thel machine. Fig. 4 is a bottom view of the same. Fig. 5 is a perspective View of a portion of the underside of the carstruction but in this case-has a transverse shaft 1 joiirnaled in the sides of the base. This shaft has at one end outside of the frame a pulley 2 and motion'isgiven' the same by a belt 3, from any suitable source of power. The shaft carries a cylinder 4 running its entire length and having reduced portions 55 at each end, through which pass set screws 66 securing the cylinder to the shaft, one of these reduced portions being also threaded as at 7 for the reception of-a nut 8, the object of which will be referred to later, The end of the cylinder opposite to the threaded portion 7 and its nut is provided with an annular flange 9 carrying a flat projection or pin 10 which extends radially beyond the periphery of the flange. Clamped on the cylinder between this flange 9 and the nut 8 is a series of rings 11 equal in number to the keylevers of the machine and Whose outer diameters are the same as the flange 9.

Each of the rings 11 has a projection or pin 12 identical in character to that marked 10 on the flange 9, and as seen in Figs. 1, 2-and 4, the rings are so placed on the cylinder that the pins 10 and 12 describe a spiral line around the cylinder from end to end and are retained in this position by the nut 8. The constantly rotating drum thus described constitutes a power driven member to which any of the type bars may be connected.

The key levers 13 of the machine constitute a selecting means to determine which type bar shall be operated by the power driven member. They are provided at their outer ends with the usual buttons or keys 14:, are fulcrumed on a transverse bar 15, and have springs 16 to restore them to their normal positions and are held against lateral movement by a transverse comb or set of pins 17 Their inner ends 18 are rounded to play against the inclined faces 19 of depending dogs or couplers 20. These dogs 20 are pivoted to the outer ends of the type bar actuating levers 21 at the points 22 and have at their pivotal portions springs 23 which force their free ends outward and tend to keep the faces 19 in contact with the ends 18 of the key levers 13. The type actuating levers 21 are connected to the type bars 24 by rods or links 24 of well known construction. The levers 21 bear upon the-universal bar 25, are fulcrumed on a bearing rib 26, and have returning springs 27 and are held from lateral play by a comb or set of pins 28.

By referring to Figs. 1, 6 and 7, the operation of the keys and type bars may be seen. The shaft 1 with its cylinder and rings is kept in constant and rapid rotation by thepower belt 3 and when a key 14 is struck, the end 18 of the lever '13 rides over the face 19 of the dog 20, forcing it inward towards the cylin der and its nose20 in the line of its corresponding pin 12 on one of the rin s 11-, or the pin 10 on the flange 9. The rapi movement of the shaft carries the pin into almost impaw 44 which cmfes near its free and mediate engagsnmn'b with the nose 20 mi em pinS which engages a mtshe'i w forms the dog down, carrying with i; fihe mounted. on shaft i? and I 2min;- a type saws-ting lever 21.

dog 2 vidod m e i eased as using is 7 TO the machine is in use and the springs on the various levers and dogs tend to keep'them in their normal positions The speed of the movement of the carriage may be determined by the throw of the pawl 44 and this is regulated by the adjusting screws 42 and 43.

The space bar 80 runs across the front of the keyboard and is carried by arms 81 pivotedon the flange like the key levers. One of said arms 81 cooperates with a dog and lever 21, but this lever of course does not operatea type bar.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent,'is

1. In a typewriting machine, the combination with a printing mechanism and a power driven member for operating the same, of a coupler pivoted to a portion of said printing mechanism and adapted to be moved by said power driven member, and a key lever havmg a cam portion for moving said coupler on its pivot to bring it into engagement with said driven member.

8. In a typewriting machine, the combination with a series of type bars, of means for operating said bars comprising a power driven member, a series of couplers for connecting any one ofsaid bars to said member, a bar for disengaging the couplers from the member, said bar being adjustable-to disengage said couplers at different points.

9.
